Shine light on the Cat’s Eye

The Cat’s Eye Nebula’s present-day popularity owes much to the Hubble Space Telescope’s dramatic portraits, though it was famous well over a century before Hubble was even conceived.


Webb: Stellar nursery in Carina

12 July 2022 Astronomy Now

The seemingly three-dimensional “Cosmic Cliffs” of the Carina Nebula showcases Webb’s capabilities to peer through obscuring dust and shed new light on how stars form.


Webb: Southern Ring Nebula comes into full view

12 July 2022 Astronomy Now

NASA’s James Webb Space Telescope has cast the Southern Ring Nebula in an entirely new light. By observing the nebula in mid-infrared wavelengths, Webb has unveiled the second, dusty star at the center of the nebula in far more detail.


Watch live: Scientists releasing more images from Webb telescope today

12 July 2022 Stephen Clark

Scientists will release additional images and data from the James Webb Space Telescope today, including ultra-sharp infrared views of a star-forming nebula, a colorful cloud of gas around a dying star, a group of distant galaxies, and the first measurement of the composition of a planet around another star. The images will be released at 3:30pm BST (1430 GMT/10:30 a.m. EDT).


Webb’s stunning Deep Field image released

11 July 2022 Astronomy Now

NASA’s James Webb Space Telescope has produced the deepest and sharpest infrared image of the distant universe to date. Known as Webb’s First Deep Field, this image of galaxy cluster SMACS 0723 is overflowing with detail. Thousands of galaxies – including the faintest objects ever observed in the infrared – have appeared in Webb’s view for the first time. This slice of the vast universe is approximately the size of a grain of sand held at arm’s length by someone on the ground. This deep field, taken by Webb’s Near-Infrared Camera (NIRCam), is a composite made from images at different wavelengths, totaling 12.5 hours – achieving depths at infrared wavelengths beyond the Hubble Space Telescope’s deepest fields, which took weeks. The image shows the galaxy cluster SMACS 0723 as it appeared 4.6 billion years ago. The combined mass of this galaxy cluster acts as a gravitational lens, magnifying much more distant galaxies behind it. Webb’s NIRCam has brought those distant galaxies into sharp focus – they have tiny, faint structures that have never been seen before, including star clusters and diffuse features. Researchers will soon begin to learn more about the galaxies’ masses, ages, histories, and compositions, as Webb seeks
